Abstract : The forecasts of demand for air travel developed using the Air Passenger Demand Model differ from other available forecasts of commercial air travel, in that they avoid dependence on analysis or extrapolation of trends observed in air travel time series data. The computer version of the model operates as three distinct phases. Phase I develops a general travel pattern and produces a four-dimensional trip table for each demand analysis area. This trip table stipulates an area's outbound trips, by purpose and by traveler income level, to each of 324 other areas for each of three points in time. Phase II systematically checks all possible routes and travel mode combinations for each trip cell to identify the least cost trip where cost includes an imputed time value for the travel time involved and records the least cost trip. Phase III tabulates the trip records and reports air trip origins for each Texas airport having scheduled air passenger service. (Modified author abstract)
